The Securities and Exchange Commission ended its investigation of stun-gun maker Taser International on Monday and announced that no enforcement action was recommended.

In December, the SEC completed an investigation into product safety issues, as well as certain accounting and disclosure matters. No enforcement action was recommended by the SEC staff at that time. The regulator said, however, that it would continue its probe into the trading of Taser stock, which began as an informal inquiry in January 2005.

The news that the SEC has ended its probe comes on the heels of a warning issued last week by Taser officials that said the company would delay its March quarterly report after discovering errors in how it calculates manufacturing expenses applied to inventory as well as a clerical error.
